Release Notes for 408

Attributes allow developers to extend instances with additional metadata and properties

InputObject::IsModifierKeyDown tells you whether modifier key was down for a given input event. Enum.ModifierKey.[Ctrl, Alt, Shift, Meta]

Implemented some changes to change Animator joint search root from "my parent's parent" to instead use the Animator's immediate parent if it is not a Humanoid or AnimationController. Also implements analytics to find games that may be affected in advance of enabling this change.

Added JointInstance.Enabled. Hidden for now. Waiting for supported clients to take over before enabling.

Add GetPlayingAnimationTracks and AnimationPlayed to Animator. Animator.AnimationPlayed is not enabled yet. Along with the model search change this eliminates the need for an AnimationController in animated models without a Humanoid.
